G.657B3 Single-mode fiber with low bending sensitivity
product description
Bend-insensitive single-mode fiber, manufactured through specialized processes, is engineered for fiber-to-the-home (FTTH), enterprise intranet networks, and applications requiring ultra-low bending radius communication. Its performance surpasses ITU-TG.657.B3 standards, delivering minimal bending-induced attenuation even at 5mm radii. This innovation addresses installation challenges in complex indoor/outdoor environments, including wall corner bends, patch cord terminations, and high-tension cable conditions, ensuring stable communication system operation.
operative norm
